Carl Barks liked to use mad or delirious scientists in his stories. It already happened that Don Rosa uses scientists invented by Barks for his own stories, and even that he invents his own scientists... I tried to make a list of all the scientists in their work :
-Professor Mollicule:
This tall bald dogfaced professor is very naive,
and he doesn't always foresee the consequencies of his experiences, a little
bit like Gyro Gearloose... He is a friend of Donald
and Scrooge. He lives in Duckburg and is of American nationality. He first
appears in Barks' "Donald Duck's Atom Bomb" (Cheerios Premiums
Giveaway, 1947), in which he brings his help to Donald? who created a new
kind of atom bomb.Then, he comes back in Don Rosa's 1991's "The Duck
Who Fell to Earth" (D 90161), in which he works for Scrooge and has
invented a new fuel which is able to burn without oxygen, which he associates
with a 1949's plane Scrooge bought by auction to travel in space... In
the second story, he seems to play Gyro's part...
The Scientists of
Duckburg's Laboratory:
In Barks' "Super Snooper" (WDC 107, 1949), Donald accidentally
drinks an isotope send by "Professor Cosmic" and destinated
to the tests center, which makes him get superpowers... Don Rosa made a
remake of this story, "Super Snooper Strikes Again" (D 91076), in
which Donald is a postman and has to bring the same isotope to the laboratory,
and we can meet two crazy scientists who work there. They are not important
character, but I wanted to include them as they're so silly :-)
-The Scientists
from Carl Barks' "Lost in the Andes" :
In Barks' "Lost in the Andes", (OS 223, 1949) we can see a bunch
of silly scientist who are dumbfounded in front of the square eggs and
chickens...
-The Scientists
from Carl Barks' "Christmas for Schacktown" :
In "A Christmas for Shacktown" (OS 367, 1952), Scrooge engages
a bunch of silly engineers to save his money because the bottom of his
Money Bin collapsed, but they can't help him, saying his money is definitely
lost... (In the new sequel of this story, "Gyro's First Invention",
by Don Rosa, Gyro Gearloose succeeds where this
whole bunch failed)
-Ipsquiggle:
In Barks' "Wily Rival" (US 34), Gyro
Gearloose goes to the patents office kept by Mr. J. Giltfilcher
to show his last invention. In the waiting-room, he meets a tall man sit
next to what should be his invention, hidden behind a sheet. He wonders
what his invention could be, and he worries about this because he is affraid
it is the same than his, or worse, it could be a better invention. Finally,
we discover that the tall man was the invention (a robot) and the thing
under the sheet is its inventor, Ipsquiggle, a funny little man
who lisps.
-Pierre de Fraud,
alias Black Pete:
In Barks' "The Inventors' Contest" (US 28), Gyro
Gearloose participates to an inventors' contest, and his rival is Black
Pete, here called Pierre de Fraud.
-Donald Duck:
Donald Duck himself has played this part in some of Barks' stories.
That was the case in "Donald Duck's Atom
Bomb" (Cheerios Premiums Giveaway, 1947), in which he invents a new
kind of atom bomb who makes hair fall down, and also in "The Mad Chemist"
(WDC 44, 1944), in which he is accidentally given a shock while playing
with the nephews to their chemistry game, which makes him believe he is
the biggest scientist in the universe, and then he creates a dangerous
explosive, the "Donaldyte", and he even builds a rocket and travels
around the moon, but he eventually wakes up and become the normal Donald
Duck he was...
-Other scientists:
I've heard about some scientists, the professors Cosmic and Gamma,
in Barks' "Rocket Race to the Moon" (WDC 93), and another scientist
who is Gyro's neighbour in "Madcap Inventors" (US 38), but I don't
have these stories, so help is welcome.
uuh... thanx!
